The results show that the turbidity of wastewater can be removed efficiently under the appropriate conditions and the quality of the treated water is quite good to meet the requirement of technological circulating water.
Corrosion-electrochemical behavior of tube stills of a 18-10 steel combined with the case component members from plain carbon steels in circulating water of petroleum refineries is investigated.
We present the results from an experimental investigation of the methods of aerodynamic action on the processes of evaporative cooling of circulating water in a cooling tower.
When circulating water was heated by ascending heat flow, gold would be extracted, concentrated and transported from auriferous rocks and then precipitated in the masses during the late tectonic movement.
We describe the water chemistry of circulation heat-transfer systems (cooling and heat-supply networks) at which the pH value of the circulation water lies in the range 7.0-8.3.
In addition, the experiment indicates that this novel chiller is highly suitable for an air conditioning system with a low dehumidification requirement or a system with a large cycle flowrate and an industrial cooling water system.
The level of physical parameters is treated that corresponds to the interaction between molten core droplets and cooling water in the case of severe accident in a nuclear reactor.
It is shown that, among the materials considered, those holding most promise for the development of adsorption systems for cooling water are new composite selective water sorbents, primarily KSKG silicagel modified with calcium chloride.
A description of promising developments of the equipment for the ball-cleaning system of turbine condensers and filters for additional cleaning of cooling water is presented.
An 8-week feeding trial was conducted in a recycling water system at 28?±?1?°C to investigate carbohydrate to lipid ratio (CHO:L ratio) in African catfish Clarias gariepinus (12.32?±?0.04?g).
Russian space scientists have done much work on closed ecological life support systems (CELSS) using higher plants and algae both for recycling water and air and regeneration of food.
